The Ultraviolet Absorption Spectra of 1ndash;3 Cyclohexadiene

摘要

The intense absorption of 1–3 cyclohexadiene in the region 35,000–45,000 cm—1has been measured in the vapor and in hexane solution, and characteristic frequency differences of the band maxima noted. Values of oscillator strength obtained from these data are consistent with theoretical predictions, but thefvalue found from the solution agrees better with that from the vapor if the correction for Lorenz‐Lorentz forces is not applied.
